Before entering fully into the meaning of the term dredge, we will proceed to know its etymological origin. In this case, we can point out that it is a word that derives from French, exactly "dredger", which can be translated as "network".

He verb dredge refers to the use of a dredge to achieve the cleaning and the deepening of a river, a lake, a canal or another body of water. The dredger, meanwhile, is the machine which allows to carry out this task by extracting rocks, sand and other materials and sediments.

When dredging, it is possible increase the depth of a waterway . In this way, navigation is facilitated, allowing large vessels to move without risk of running aground. That is why these tasks are necessary in the ports : If it is intended to receive cruises of enormous dimensions, for example, it is likely that dredging will be required.

Dredging, on the other hand, grants greater transfer capacity of Water to the road in question. This minimizes the possibility of flooding in the surrounding areas.

There are different types of dredgers according to the characteristics of the ground to dredge Some of these machines are installed in mainland , while others work from boats .

What is done when dredging is dig a material that is submerged, removing it and bringing it to the surface. This action It results in an increase in the depth of the body of water and a decrease in its level.

Between the mechanical dredgers , the excavator dredgers , the front loading shovel dredgers , the continuous hopper dredgers and the spoon dredgers . At group of the suction dredgers , for its part, we can find the suction dredgers underway , the stationary suction dredgers and the cutting dredgers .

It is interesting to establish, in addition to everything indicated, that dredger was a machine that was responsible for designing the great genius Leonardo da Vinci. Specifically, it responded to the name of lagoon dredger and it was an excavator responsible for cleaning the bottom of certain channels.

Its operation and principle was similar to that of the dredgers that exist today and was based on the use of a series of buckets that acted one after the other and that while digging allowed dirt and collected material to be stored in devices that responded to the name of storage floats.

Nowadays a model of this type of contraption that responds to the name of dredger van veen is well known. This is achieved by obtaining samples of surface sediments in medium-hard or soft bottoms. Specifically, it is used very frequently in both biological and other hydrological studies and even those that are framed within the environmental field.

Its appearance is that of two spoons that are connected through a hinge. Those are separated, but come together to collect sediment samples.
